You may have heard the joke that asserts a camel is just a horse designed by a committee. The truth behind the humor is that groups suffer from something called "groupthink," which means they tend to lose the benefits of independent thought and just agree with each other. Everyone ends up patting themselves on the back rather than creating something great. Amazon founder and CEO Jeff Bezos solves that problem with a two-pizza rule.

According to productivity and ideas blog the 99u, Bezos uses pizza as a metric for choosing the size of his teams. Basically, if a team can't be fed be two pizzas alone that team is too large. The brain can't handle a lot of people, so it's not a surprise that smaller teams tend to work better. If you find independent ideas are suffering in your organization, it might be time to suggest instituting the two pizza rule. At the very least, you might get a free meal out of it.
